3 Product OverviewBanner's SGS Safety Grid System is a two-piece, redundant, microprocessor-controlled, retroreflective optoelectronic "light grid". Standard models are available in 2beam (500 mm beam spacing), 3 beam (400 mm beam spacing), or 4 beam (300 mmand 400 mm beam spacing) systems.

The emitter's modulated infrared (invisible) light-emitter diodes (LEDs) and the receiversphotodetectors are contained in a robust metal housing (active side of the system). Thepassive side of the system contains mirrors inside a robust metal housing.

The SGS can be configured for Trip Output (Automatic start/restart) or Latch Output(Manual start/restart). In typical operation, if any part of an operator's body (or anyopaque object) of more than a pre-determined cross section is detected, the solid-stateoutput signal switching device (OSSD) safety outputs turn Off. These safety outputs areconnected to the guarded machine's final switching devices (FSDs) that control themachine primary control elements (MPCEs), which immediately stop the motion of theguarded machine.

SGS sensors are extensively FMEA (Failure Mode and Effects Analysis) tested toestablish an extremely high degree of confidence that when properly installed, nosystem component (even if it should ever fail) can cause a failure to danger.

SGS systems do not require an external controller when using the external devicemonitoring (EDM) function. This function ensures the fault detection capability requiredby U.S. Control Reliability and ISO 13849-1 Categories 3 or 4 and PL d or e forcontrolling final switching devices (FSDs) or Machine Primary Control Elements(MPCEs).

When the SGS is connected to a self-checking safety module, safety controller, orsafety PLC/PES, that conforms to the level of performance required by the riskassessment, the EDM function of the SGS is not used. Examples include the UM-FA-9A/-11A safety module, SC10-2roe or XS/SC26-2 safety controller for applicationsrequiring Control Reliability and/or ISO 13849-1 Categories 3 or 4 and PL d or e.

Electrical connections (power, ground, inputs and outputs) are made via M12 quick-disconnect cordsets.

The active unit features a 7-segment Diagnostic Display and individual LEDs to provide continuous indication of operatingstatus, configuration, and error conditions.

3.1 ModelsAn SGS Safety Grid System refers to a compatible active and passive unit of equal length and resolution, including theircordsets and mounting hardware (ordered separately). Interfacing solutions include IM-T-9A/11A modules, SR-IM-9A/11Amodules, redundant positively guided contactors, safety modules/controllers, and muting modules.

The Active Transceiver and Mirror Assembly components of the SGS Safety Grid System are ordered separately. Acomplete system is composed of the following items:

3.2 Appropriate Applications and Limitations

WARNING: Read this Section Carefully Before Installing the System

If all mounting, installation, interfacing, and checkout procedures are not followed properly, the Bannerdevice cannot provide the protection for which it was designed. The user is responsible for ensuring thatall local, state, and national laws, rules, codes, or regulations relating to the installation and use of thiscontrol system in any particular application are satisfied. Ensure that all legal requirements have beenmet and that all technical installation and maintenance instructions contained in this manual are followed.

The user has the sole responsibility to ensure that this Banner device is installed and interfaced to theguarded machine by Qualified Persons1, in accordance with this manual and applicable safetyregulations. Failure to follow these instructions could result in serious injury or death.

The Banner SGS is intended for safeguarding applications as determined by a risk assessment. It is the user’s responsibilityto verify whether the safeguarding is appropriate for the application and is installed, as instructed by this manual, by aQualified Person.

The SGS ability to perform its safeguarding function depends upon the appropriateness of the application and upon itsproper mechanical and electrical installation and interfacing to the guarded machine. If all mounting, installation, interfacing,and checkout procedures are not followed properly, the SGS cannot provide the protection for which it was designed.

WARNING:• Access and Perimeter Safeguard Installation• Failure to follow these instructions could result in serious injury or death.• If an SGS Safety Grid System is installed for use as an access or perimeter guard (where a pass-

through hazard may exist, see Reducing or Eliminating Pass-Through Hazards (p. 13)),configure the SGS for Manual Start/Restart (Latch Output). The dangerous machine motion canbe initiated by normal means only after the safeguarded area is clear of individuals and the SGSSafety Grid System has been manually reset.

3.2.1 Appropriate ApplicationsThis SGS Safety Grid System is typically used in access guarding and perimeter guarding applications. Some potentialapplications are:

• Automated production equipment• Robotic work cells• Palletizers• Assembly and packaging machines• Lean manufacturing systems• Automated warehouses

3.2.2 Examples: Inappropriate ApplicationsDo not use the SGS in the following applications:

1 A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training andexperience, has successfully demonstrated the ability to solve problems relating to the subject matter and work.



• With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or full-revolution) clutched machinery

• With any machine with inadequate or inconsistent machine response time and stopping performance• With any machine that ejects materials or component parts through the defined area• In any environment that is likely to adversely affect photoelectric sensing efficiency. For example, corrosive

chemicals or fluids or unusually severe levels of smoke or dust, if not controlled, may degrade sensing efficiency• As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control

system fully comply with the relevant standard or regulation (see OSHA 29CFR1910.217, ANSI/NFPA 79, ANSIB11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)

3.2.3 Control Reliability: Redundancy and Self-CheckingRedundancy requires that the SGS circuit components be backed up to the extent that, if the failure of a single componentwill prevent effective machine stopping action when needed, that component must have a redundant counterpart which willperform the same function. The SGS is designed with redundant microprocessors.

Redundancy must be maintained whenever the SGS is in operation. Because a redundant system is no longer redundantafter a component has failed, the SGS is designed to monitor itself continuously. A component failure detected by or withinthe self-checking system causes a stop signal to be sent to the guarded machine and puts the SGS into a Lockoutcondition.

A recovery from this type of Lockout condition requires:• Replacement of the failed component (to restore redundancy)• The appropriate reset procedure

The Diagnostic Display is used to diagnose causes of a Lockout condition. See Troubleshooting (p. 37).

3.3 Operating FeaturesThe Banner SGS Safety Grid System models described in this manual feature several functions.

3.3.1 Selectable Auto or Manual Start/RestartThe setting for Automatic Start/Restart (Trip Output) or Manual Start/Restart (Latch Output) determines if the SGS entersRun mode automatically or if a manual reset is required first. If the SGS is set for Trip Output, other measures must be takento prevent a pass-through hazard. For more information, see Reducing or Eliminating Pass-Through Hazards (p. 13).

If Automatic Start/Restart (Trip Output) is selected, the output signal switching device (OSSD) outputs turn on after power isapplied, and the active transceiver passes its internal self-test/synchronization and recognizes that all beams are clear. TheOSSD outputs also turn on after all beams are cleared following a blocked beam.

If Manual Start/Restart (Latch Output) is selected, the SGS requires a manual reset for the OSSD outputs to turn on whenpower is applied and all beams are clear or after a blocked beam has been cleared.

Factory Default Setting: Manual Start/Restart

WARNING: Use of Auto (Trip) or Manual (Latch) Start/Restart

Application of power to the Banner device, the clearing of the sensing field, or the reset of a manualstart/restart (latch) condition MUST NOT initiate dangerous machine motion. Machine control circuitrymust be designed so that one or more initiation devices must be engaged (in a conscious act) to start themachine – in addition to the Banner device going into Run mode. Failure to follow these instructionscould result in serious injury or death.

3.3.2 External Device Monitoring (EDM)The external device monitoring (EDM) feature allows the SGS to monitor the status of external devices, such as final switchdevices (FSD) and machine primary control elements (MPCE). The choices are 1-channel monitoring or no monitoring. EDMis used when the SGS OSSD outputs directly control the FSDs, MPCEs, or other external devices.

Factory default setting: 1-channel monitoring

3.3.3 Status IndicatorsThe active unit's status indicators are on the front panel.



Active Transceiver

1-Digit Diagnostic Display—indicates configuration or specific errorconditions.

Green Status—Indicates when all the OSSD outputs are on.

4 Mechanical InstallationThe SGS system performance as a safety guarding device depends on:

• The suitability of the application• The proper mechanical and electrical installation and interfacing to the guarded machine

WARNING: Read this Section Carefully Before Installing the System



4.1 Mechanical Installation ConsiderationsThe two primary factors that influence the layout of the SGS system mechanical installation are the Safety Distance(Minimum Distance) (see Calculating Safety Distance Formula and Examples (p. 12)) and the supplemental safeguarding/eliminating pass-through hazards (see Reducing or Eliminating Pass-Through Hazards (p. 13)). Other considerationsinclude:

• Active Transceiver to Mirror Assembly Orientation Active Transceiver and Mirror Assembly Orientation (p. 17))• Adjacent Reflective Surfaces (see Adjacent Reflective Surfaces (p. 15))• Use of Corner Mirrors (see Use of Corner Mirrors (p. 16))• Installation of Multiple Systems (see Installing Adjacent Systems (p. 18))

WARNING: The Hazard Must Be Accessible Only through the Sensing Field

The installation of the SGS must prevent any individual from reaching around, under, over or through thesensing field and into the hazard without being detected. Mechanical barriers (for example, hard (fixed)guarding) or supplemental safeguarding may be required to comply with this requirement, and isdescribed by ANSI B11.19 safety requirements or other appropriate standards. Failure to follow theseinstructions could result in serious injury or death.

4.1.1 Safety (Minimum) DistanceSafety Distance (Ds), also called Minimum Distance (S), is the minimum distance required between the SGS sensing fieldand the closest reachable hazard point. The distance is calculated so that when an object or a person is detected (byblocking a sensing beam), the SGS sends a stop signal to the machine, causing it to stop by the time the object or personcan reach any machine hazard point.

The distance is calculated differently for U.S. and European installations. Both methods take into account several factors,including a calculated human speed, the total system stopping time (which itself has several components), and the depthpenetration factor. After the distance has been determined, record the calculated distance on the Daily Checkout Card.

WARNING:• Safety Distance (Minimum Distance)• Failure to establish and maintain the minimum distance could result in serious injury or death.• Mount the Banner active transceivers and mirror assemblies at a distance from the nearest

hazard such that an individual cannot reach the hazard before cessation of hazardous motion orsituation. Calculate this distance using the formulas as described by ANSI B11.19 and ISO13855.




4.1.2 Calculating Safety Distance Formula and ExamplesU.S. Applications European Applications

The Safety (Separation) Distance formula for U.S. applications:

Ds = K × (Ts + Tr) + Dpf

The Minimum Distance formula for European applications:

S = (K × T) + C

Ds

the Safety Distance

K

1600 mm per second (or 63 in per second), the OSHA29CFR1910.217, and ANSI B11.19 recommended approach speedconstant (see Note 1 below)

Ts

the overall stop time of the machine (in seconds) from the initialstop signal to the final ceasing of all motion, including stop timesof all relevant control elements (for example, IM-T-.. InterfaceModules) and measured at maximum machine velocity (see Note 3below)

Tr

the maximum response time, in seconds, of the SGS activetransceiver (depending on model)

Dpf

the added distance due to the depth penetration factor asprescribed in OSHA 29CFR1910.217, and ANSI B11.19 for U.S.applications

Dpf is 900 mm (36 in) for reach-through applications if the top ofthe sensing field cannot be reached over and the bottom beam isno more than 300 mm (12 in) above the floor

Dpf is 1200 mm (48 in) for reach-over applications where the topof the sensing field is between 900 mm (36 in) and 1200 mm (48 in)above the floor and the bottom beam is no more than 300 mm (12in) above the floor

S

the Minimum Distance, in mm, from danger zone to SGS sensingfield center line

K

1600 mm per second recommended approach speed constant(see Note 2 below)

T

the overall machine stopping response time (in seconds), from thephysical initiation of the safety device and the machine coming toa stop (or the hazard removed). This can be broken down into twoparts: Ts and Tr where T = Ts + Tr

C

the additional distance, in mm, based on intrusion of a hand orobject towards the danger zone prior to actuation of a safetydevice. Calculate using the formula (in mm):

C = 850

since the resolution is greater than 40 mm.

Notes:

1. The OSHA-recommended approach speed constant K has been determined by various studies and, although thesestudies indicate speeds of 1600 mm/sec. (63 in/sec.) to more than 2500 mm/sec. (100 in/sec.), they are notconclusive determinations. Consider all factors, including the physical ability of the operator, when determining thevalue of K to be used.

2. The recommended approach speed constant K, derived from data on approach speeds of the body or parts of thebody as stated in ISO 13855.

3. Ts is usually measured by a stop-time measuring device. If the machine manufacturer's specified stop time is used,at least 20% should be added to allow for possible clutch/ brake system deterioration. This measurement must takeinto account the slower of the two MPCE channels, and the response time of all devices or controls that react tostop the machine.



Example Calculation

US Application example: Model SGSxA4-400xxx

K = 1600 mm/s (63 in/s)

Ts = 0.32 (0.250 seconds is specified by the machine manufacturer; plus20% safety factor; plus 20 ms interface module IM-T-9A response)

Tr = 0.012 seconds (the specified SGSxA4-400xxx response time)

Dpf = 900 mm (36 in)

Ds = 1600 × (0.32 + 0.012) + 900 = 1432 mm (57 in)

Mount the SGS active transceiver and mirror assembly so that no part ofthe sensing field is closer than 1432 mm (57 in) to the closest reachablehazard point on the guarded machine.

European Application example: Model SGSxA4-400xxx

K = 1600 mm per second

T = 0.332 (0.250 seconds is specified by the machine manufacturer;plus 20% safety factor; plus 20 ms interface module IM-T-9A response),plus 0.012 seconds (the specified SGSxA4-400xxx response time)

C = 850 mm

S = (1600 × 0.332) + 850 = 1382 mm

Mount the SGS active transceiver and mirror assembly so that no part ofthe sensing field will be closer than 1382 mm to the closest reachablehazard point on the guarded machine.

WARNING: Determine Correct Stop Time

Stop time (Ts) must include the response time of all devices or controls that react to stop the machine. Ifall devices are not included, the calculated safety distance (Ds or S) will be too short. Failure to followthese instructions could result in serious injury or death. Be sure to include the stop time of all relevantdevices and controls in your calculations.

If required, each of the two Machine Primary Control Elements (MPCE1 and MPCE2) must be capable ofimmediately stopping the dangerous machine motion, regardless of the state of the other. These twochannels of machine control need not be identical, but the stop time performance of the machine (Ts,used to calculate the safety distance) must take into account the slower of the two channels.

4.1.3 Reducing or Eliminating Pass-Through HazardsA pass-through hazard is associated with applications where personnel may pass through a safeguard, such as the SGSSafety Grid System (which issues a stop command to remove the hazard), and then continues into the guarded area. This iscommon in access and perimeter guarding applications. Subsequently, their presence is no longer detected, and therelated danger becomes the unexpected start or restart of the machine while personnel are within the guarded area.

A pass-through hazard typically results from large safety distances calculated from long stopping times, large minimumobject sensitivities, reach-over, reach-through, or other installation considerations. A pass-through hazard can be generatedwith as little as 75 mm (3 in) between the sensing field and the machine frame or hard (fixed) guarding.

Eliminate or reduce pass-through hazards whenever possible. While it is recommended to eliminate the pass-throughhazard altogether, this may not be possible due to machine layout, machine capabilities, or other applicationconsiderations.

One solution is to ensure that personnel are continually sensed while within the hazardous area. This can be accomplishedby using supplemental safeguarding, such as described by the safety requirements in ANSI B11.19 or other appropriatestandards.

An alternative method is to ensure that once the safeguarding device is tripped it will latch and will require a deliberatemanual action to reset. This method of safeguarding relies upon the location of the reset switch as well as safe workpractices and procedures to prevent an unexpected start or restart of the guarded machine. The SGS Safety Grid Systemprovides a configurable Manual Start/Restart (Latch Output) function for these applications.

WARNING:• Use of the Banner device for Access or Perimeter Guarding• Failure to observe this warning could result in serious injury or death.• If a Banner device is installed in an application that results in a pass-through hazard (for example,

perimeter guarding), either the Banner device or the Machine Primary Control Elements (MPCEs)of the guarded machine must cause a Latched response following an interruption of the definedarea.

• The reset of this Latched condition may only be achieved by actuating a reset switch that isseparate from the normal means of machine cycle initiation.



WARNING:• Perimeter guarding applications• Failure to observe this warning could result in serious injury or death.• Use lockout/tagout procedures per ANSI Z244.1, or use additional safeguarding as described by

ANSI B11.19 safety requirements or other applicable standards if a passthrough hazard cannotbe eliminated or reduced to an acceptable level of risk.

4.1.4 Supplemental SafeguardingAs described, the SGS must be properly positioned such that an individual cannot reach through the sensing field andaccess the hazard point before the machine has stopped.

Additionally, the hazard cannot be accessible by reaching around, under, or over the sensing field. To accomplish this,supplemental guarding (mechanical barriers, such as screens or bars), as described by ANSI B11.19 safety requirements orother appropriate standards, must be installed. Access will then be possible only through the sensing field of the SGSSystem or through other safeguarding that prevents access to the hazard.

The mechanical barriers used for this purpose are typicallycalled "hard (fixed) guarding"; there must be no gapsbetween the hard (fixed) guarding and the sensing field. Anyopenings in the hard (fixed) guarding must comply with thesafe opening requirements of ANSI B11.19 or otherappropriate standard.

This example shows an example of supplementalsafeguarding inside a robotic work cell. The SGS, inconjunction with the hard (fixed) guarding, is the primarysafeguard. Supplemental safeguarding (such as ahorizontal-mounted safety light screen as an area guard) isrequired in areas that cannot be viewed from the resetswitch (for example, behind the robot and the conveyor).Additional supplemental safeguarding may be required toprevent clearance or trapping hazards (for example, a safetymat as an area guard between the robot, the turntable, andthe conveyor).

WARNING:• The hazard must be accessible only through the sensing field• Incorrect system installation could result in serious injury or death.• The installation of the SGS must prevent any individual from reaching around, under, over or

through the defined area and into the hazard without being detected.• See OSHA CFR 1910.217, ANSI B11.19, and/or ISO 14119, ISO 14120 and ISO 13857 for

information on determining safety distances and safe opening sizes for your guarding device.Mechanical barriers (for example, hard (fixed) guarding) or supplemental safeguarding might berequired to comply with these requirements.

4.1.5 Reset Switch LocationMount the reset switch at a location that complies with the warning and guidelines below. If any hazardous areas are not inview from the switch location, additional means of safeguarding must be provided. The switch should be protected fromaccidental or unintended actuation (for example, through the use of rings or guards).

A key-actuated reset switch provides some operator or supervisory control, as the key can be removed from the switch andtaken into the guarded area. However, this does not prevent unauthorized or inadvertent resets due to spare keys in thepossession of others, or additional personnel entering the guarded area unnoticed. When considering where to locate thereset switch, follow the guidelines below.



WARNING: Reset Switch Location

When considering where to locate the reset switch, you must follow the guidelines outlined in thissection.

If any areas within the guarded area are not visible from the reset switch, additional safeguarding mustbe provided, as described by the ANSI B11.19 series or other appropriate standards.

Failure to follow these instructions could result in serious injury or death.

All reset switches must be:• Outside the guarded area• Located to allow the switch operator a full, unobstructed, view of the entire guarded area while the reset is

performed• Out of reach from within the guarded area• Protected against unauthorized or inadvertent operation (such as through the use of rings or guards).

Important: Resetting a safeguard must not initiate hazardous motion. Safe work procedures require astart-up procedure to be followed and the individual performing the reset to verify that the entirehazardous area is clear of all personnel before each reset of the safeguard is performed. If any areacannot be observed from the reset switch location, additional supplemental safeguarding must be used:at a minimum, visual and audible warnings of machine start-up.

4.1.6 Adjacent Reflective Surfaces

WARNING: Avoid Installation Near Reflective Surfaces

Avoid locating the sensing field near a reflective surface; it could reflect sensing beam(s) around anobject or person within the sensing field, and prevent its detection by the SGS. Perform the trip test, asdescribed in the manual, to detect such reflection(s) and the resultant optical short circuit. Failure toprevent reflection problems will result in incomplete guarding and could result in serious injury or death.

A reflective surface located adjacent to the sensing field may deflect one or more beams around an object in the sensingfield. In the worst case, an optical short circuit may occur, allowing an object to pass undetected through the sensing field.

This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, thefloor, or the walls. Beams deflected by reflective surfaces are discovered by performing the trip test and the periodiccheckout procedures. To eliminate problem reflections:

• If possible, relocate the sensors to move the beams away from the reflective surface(s), being careful to maintainadequate separation distance

• Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reflectivity• Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resolution

resulting from the optical short circuit and use the corresponding depth penetration factor (Dpf or C) in the SafetyDistance (Minimum Distance) formula; or mount the sensors in such a way that the receiver's field of view and/or theemitter's spread of light are restricted from the reflective surface

• Repeat the trip test (see Trip Test under Initial Checkout Procedure (p. 22)) to verify these changes have eliminatedthe problem reflection(s). If the workpiece is especially reflective and comes close to the sensing field, perform thetrip test with the workpiece in place

4.1.7 Use of Corner MirrorsSGS may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow undetectedpersonnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum specified activetransceiver/mirror assembly separation by approximately 8 percent per mirror, as follows:

Table 2: SSM Series Glass-Surface Mirrors 3 —Maximum Active Transceiver and Mirror Assembly Separation

8 meters max range (m) 6.5 meters max range (m)

1 7.36 5.98

2 6.77 5.5

3 6.23 5.06

If mirrors are used, the difference between the angle of incidence from the active transceiver to the mirror and from themirror to the mirror assembly must be between 45° and 120°. If placed at a sharper angle, an object in the light screen maydeflect beam(s) to the mirror assembly, preventing the object from being detected, also know as false proxing. Anglesgreater than 120° result in difficult alignment and possible optical short circuits.

WARNING:• Avoid Retroreflective Installation• Sensing may be unreliable in this configuration and could result in a serious injury or death.• Do not install active transceivers and mirror assemblies in retroreflective mode, with less than a

45° angle of incidence, as shown.

4.1.8 Active Transceiver and Mirror Assembly OrientationMount the Active Transceiver and Mirror Assembly parallel to each other and aligned in a common plane, with both labeledends pointing in the same direction (labeling/marking is found on the back of the units). Never mount the Mirror Assemblywith its labeled end oriented in the opposite direction of the labeled end of the Active Transceiver. If this occurs, voids in theSGS sensing field may allow objects or personnel to pass through the defined area undetected. Verify the SGS Safety GridSystem completely covers all access to the hazard point that is not already protected by hard (fixed) guarding or othersupplemental guarding.

WARNING:• Proper Orientation of the Active Transceivers and Mirror Assemblies• Failure to orient the SGS active transceivers and mirror assemblies properly will impair the

performance of the SGS Safety Grid System and will result in incomplete guarding, which couldresult in serious injury or death.

• Install SGS active transceivers and mirror assemblies with their corresponding labeled endspointing in the same direction (for example, both labeled ends facing down).

Figure 6. Installation of Multiple Systems

When two or more SGS system pairs are adjacent to one another,optical crosstalk may take place between the systems. The only way toeliminate the potential for optical crosstalk is by adding a mechanical(opaque) barrier between systems.

WARNING:• System may synchronize to a signal from

the wrong unit• If an opaque barrier is not installed, a

system may synchronize to the signal fromthe wrong unit, reducing the safety functionof the light screen. This situation isdiscovered by performing the trip test.Failure to follow these instructions couldresult in serious injury or death.

• In situations where multiple systems aremounted close together, or where asecond system is in view (within +/- 5degrees) and within range of an adjacentsystem, install a physical opaque barrier.

4.2 Mounting System Components

4.2.1 Mounting HardwareAfter the mechanical layout consideration of Mechanical Installation Considerations (p. 11) are addressed, mount thesensors and route the cables. SGS Active/Passive systems can be spaced from a minimum of 0.5 m to a maximumdistance of either 6.5 m or 8 m, depending on the SGS model.

The end mount bracket kit is ordered separately. The end mount brackets allow 360 degree rotation.



4.2.2 Mounting the End-Mount Brackets

Figure 7. End-Mount Brackets

• See Sensor Mounting and Mechanical Alignment (p. 19) for additionalmounting recommendations.

• The labeled ends of both assemblies must point in the same direction.• Four brackets are supplied with each SGSA-MBK-10-4 kit ordered.

1. Mount the bottom brackets to the desired surfaces using user-suppliedhardware.

2. Place the sensors into the bottom bracket and temporarily tightenenough to secure the sensors but allow for adjustment.

3. Verify that the sensor windows directly face each other by rotating thesensor(s), then tighten the nut on the bottom bracket.

4. Measure from a reference plane, for example, a level building floor, tothe same point(s) on the sensors to verify their mechanical alignment.Use a carpenter's level, a plumb bob, or the optional LAT-1-SGS LaserAlignment Tool (see Alignment Aids (p. 47)) or check the diagonaldistances between the sensors, to achieve mechanical alignment. See Sensor Mounting and Mechanical Alignment (p. 19).

5. Place the top brackets on the top of the sensors, attach to themounting surface using user-supplied hardware, and temporary tightenthe nut on the bracket to secure the sensors in place but allow foradjustment. Final alignment procedures are explained in InitialCheckout Procedure (p. 22).

4.2.3 Sensor Mounting and Mechanical Alignment

Verify that:• The components are directly opposite each other• Nothing is interrupting the defined area• The defined area is the same distance from a

common reference plane for each sensor• The components are in the same plane and are

level/plumb and square to each other (vertical orinclined at the same angle, and not tilted front-to-back or side-to-side)

5 Electrical Installation and TestingWARNING: Read this Section Carefully Before Installing the System



WARNING: Multiple Pairs of Sensors

Do not connect multiple pairs of sensors to one Interface Module (for example, IM-T-9A/-11A) orotherwise parallel OSSD outputs. Connection of multiple OSSD safety outputs to a single device couldresult in serious injury or death.

The following are the main steps to electrically install the SGS components and interface with the guarded machine:

1. Routing cordsets and making initial electrical connections (see Routing Cordsets (p. 21) and Initial ElectricalConnections (p. 22)).

2. Apply power to the active transceiver (see Initial Electrical Connections (p. 22)).3. Perform an Initial Checkout Procedure (see Initial Checkout Procedure (p. 22)).4. Make all electrical interface connections to the guarded machine (see Electrical Connections to the Guarded

Machine (p. 27)).5. Perform a commissioning checkout procedure (see Perform a Commissioning Checkout (p. 40)).

5.1 Routing CordsetsAttach the required cordsets to the sensors and route the sensor cables to the junction box, electrical panel, or otherenclosure in which the interface module, the redundant mechanically linked interposing relays, FSDs, or other safety-relatedparts of the control system are located. This must be done per local wiring code for low-voltage dc control cables and mayrequire installation of electrical conduit. See Accessories (p. 44) for selection of Banner-supplied cables.

The SGS is designed and manufactured to be highly resistant to electrical noise and to operate reliably in industrial settings.However, extreme electrical noise may cause a random Trip condition; in extreme cases, a Lockout is possible.

Active transceiver wiring is low voltage; routing the sensor wires alongside power wires, motor/servo wires, or other highvoltage wiring may inject noise into the SGS System. It is good wiring practice, and sometimes may be required by code, toisolate active transceiver cables from high-voltage wires, avoid routing cables close to “noisy” wiring, and provide a goodconnection to earth ground.

Sensor cabling and any interconnect wiring should have an insulation temperature rating of at least 90 °C (194 °F). Themaximum machine interface cable length is 70 m.




5.2 Initial Electrical Connections

WARNING:• Risk of electric shock• Use extreme caution to avoid electrical shock. Serious injury or death could result.• Always disconnect power from the safety system (for example, device, module, interfacing, etc.),

guarded machine, and/or the machine being controlled before making any connections orreplacing any component. Lockout/tagout procedures might be required. Refer to OSHA29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy.

• Make no more connections to the device or system than are described in this manual. Electricalinstallation and wiring must be made by a Qualified Person5 and must comply with the applicableelectrical standards and wiring codes, such as the NEC (National Electrical Code), ANSI NFPA79,or IEC 60204-1, and all applicable local standards and codes.

Lockout/tagout procedures may be required (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate standardfor controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC, NFPA79 orIEC60204-1. A functional earth is available on the green wire of the M12 connector. This ground can be connected or leftopen (floating) to achieve the best electromagnetic compliance for a specific application.

Make the electrical connections in the order described in this section. Do not remove end-caps; no internal connections areto be made. All connections are made through the quick disconnect connections.

Active Transceiver Cordset—8-pin

Connect the OSSD outputs to the IM module or other controlled relays but make sure that power is not available tothe guarded machine.

For the initial power-up and checkout, External Device Monitoring (EDM) must be configured/wired (see ExternalDevice Monitoring (p. 29)) and the reset line must be connected to +24 V dc via a NC switch.

Take precautions to prevent unused wires from shorting to ground or to other sources of energy (for example,terminate with a wire-nut). Complete the final output wiring later.

5.3 Initial Checkout ProcedureThe initial checkout procedure must be performed by a Qualified Person. It must be performed only after configuring theSystem and after connecting the components.

Perform this procedure to:• Ensure proper installation when the System is first installed• Ensure proper System function whenever any maintenance or modification is performed on the System or on the

machinery that is guarded by the System.

5.3.1 Configuring the System for Initial CheckoutFor the initial checkout, the SGS System must be checked without power available to the guarded machine. Final interfaceconnections to the guarded machine cannot take place until the light screen system has been checked out. This mayrequire lockout/tagout procedures (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard forcontrolling hazardous energy). The output connections will be made after the initial checkout procedure has beensuccessfully completed.

Verify that:• The reset line (violet wire) is connected via a NC switch to +24 V dc• Power has been removed from (or is not available to) the guarded machine and its controls or actuators• EDM is configured and wired per application requirements (1-channel or no monitoring, see External Device

Monitoring (p. 29))• If no EDM is configured, do not connect the OSSD lines to the machine control circuit. If 1-channel EDM is

configured, wire the OSSD to relays but power must not be available to the guarded machine (permanentconnections will be made later).




5.3.2 Apply (Initial) Power to the System1. Inspect the area near the light screen for reflective surfaces, including work pieces and the guarded machine.

Reflective surfaces may cause light beams to reflect around a person in the light screen, preventing the person frombeing detected and not stopping the machine motion (see Adjacent Reflective Surfaces (p. 15)).

2. Eliminate the reflective surfaces as much as possible by relocating, painting, masking, or roughening them.Remaining problem reflections will become apparent during the trip test.

3. Verify that power is removed from the SGS Safety Grid System System and from the guarded machine.4. Remove all obstructions from the light screen.5. With the power to the guarded machine Off, make external device monitoring (EDM), power, and earth ground

connections on the active transceiver cable (see Reference Wiring Diagrams (p. 30)).

Connect the +24 V dc (brown wire) and 0 V dc (blue wire) to a SELV-rated supply and connect the ground (greenwire) to earth ground. See Specifications (p. 42) for power supply requirements. If the installation does not allowdirect connection to earth ground via the cordset, provide the earth ground via the mounting brackets. Connect thereset line (violet wire) via a NC switch to +24 V dc. If 1-channel EDM is configured, wire the OSSDs to the controllingrelays.

6. Power up the SGS Safety Grid System only.7. Verify the input power is present to the active transceiver.

At least one indicator on the active transceiver should be On and the start-up sequence should cycle.8. Watch the active transceiver status and alignment to determine the light screen alignment status.9. Optically align the components.

5.3.3 Optically Align the Components

CAUTION: Ensure no individuals are exposed to any hazard if the OSSD outputs turn ON when the SGSsystem aligns.

Verify the optimal alignment, adjusting the sensor rotation with the power on. (It is easiest to align in trip mode.) At power-up, all indicators are tested (cycle).

1. Verify the active transceiver and mirror assembly are pointed squarely at each other. Use a straight edge (forexample, a level) to determine the direction the sensor is facing. The sensor face must be perpendicular to theoptical axis.

2. Enter Alignment mode by holding the NC Reset Switch open during the power-on sequence for at least 0.5 s past

the power being applied.

If the components are not aligned, the Last Couple and First Couple lights are on, the green status light is off, thered status light is on, and the 7-segment display shows an A.



3. On the active transceiver: If the green Status light is on, the red status light is off, and a 4 shows on the display, goto the next step. If not, rotate each sensor (one at a time) left and right until the green Status indicator is on and thehighest number shows on the display. The better the alignment, the faster the amber light in the end cap flashes. (Asthe sensor rotates out of alignment, the red Status indicator turns on).

4. To optimize alignment and maximize excess gain, slightly loosen the sensor mounting screws and rotate one sensor

left and right, noting the positions in each arc where the Status indicators turn red (blocked condition). Repeat withthe other sensor. Center each sensor between those two positions and tighten the mounting screws, making sure tomaintain the positioning as the screws are tightened.

Straight Edge

5. For situations where alignment is difficult, use an LAT-1-SGS Laser Alignment Tool to assist or confirm alignment by

providing a visible red dot along the sensor’s optical axis.6. After alignment is complete, cycle power to return to normal operation.

5.3.4 Optically Align the Components with MirrorsSGS sensors may be used with one or more corner mirrors for guarding more than one side of an area. The SSM-... rear-surface glass mirrors are rated at 85% efficiency. Thus, excess gain and sensing range are reduced when using mirrors; see Use of Corner Mirrors (p. 16).

During any adjustments, allow only one individual to adjust any one item at any one time.

In addition to the standard optical alignment procedure, verify:

1. The active transceiver, mirror assembly, and all mirrors are level and plumb.2. The middle of the defined area and the center point of the mirrors are approximately the same distance from a

common reference point, such as the same height above a level floor.3. There are equal amounts of mirror surface above and below the defined area such that the optical beams are not

passing below or above the mirror.

Note: A LAT-1-SGS Laser Alignment Tool is very helpful by providing a visible red dot along the opticalaxis. See Banner Safety Applications Note SA104 (p/n 57477) for further information.

5.3.5 Conduct a Trip TestAfter optimizing the optical alignment, perform the trip test to verify the detection capability of the SGS system.

This test also verifies correct sensor orientation and identifies optical short circuits. After the installation has passed the triptest, the safety outputs may be connected and the commissioning checkout may be performed (initial installations only).

1. Verify the system is in Run mode and the Green Status indicator is on.2. Pass the test piece through each beam in three paths: near the mirror assembly, near the active transceiver, and

midway between the two components. Use a 60 mm or larger diameter test piece (not supplied).

Test Piece

Figure 11. Trip Test

During each pass, while the test piece is interrupting each beam, the red Status indicator should turn on and thegreen indicator should turn off. If this does not happen, the installation has failed the trip test. Check for correctsensor orientation and reflective surfaces. When the test piece is removed from the sensing field, in trip outputoperation, the green Status indicator must turn on and the red indicator turn off.

WARNING: If the Trip Test Indicates a Problem

If the SGS System does not respond properly to the trip test, do not attempt to use the System. Ifthis occurs, the System cannot be relied on to stop dangerous machine motion when a person orobject enters the sensing field. Failure to follow these instructions could result in serious injury ordeath.

3. If mirrors are used in the application, test the sensing field on each leg of the sensing path (for example, betweenmirror assembly to mirror, between mirror and active transceiver).

4. If the SGS System passes all checks during the trip test, go on to Electrical Connections to the Guarded Machine (p.27).



5.4 Electrical Connections to the Guarded MachineVerify that power has been removed from the SGS and the guarded machine. Make the permanent electrical connections asdescribed in OSSD Output Connections (p. 27) and FSD Interfacing Connections (p. 27) as required by each individualapplication.

Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, ISO 14118, or the appropriatestandard for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC,NFPA79 or IEC 60204-1.

Supply power and external device monitoring (EDM) should already be connected. The SGS must also have been alignedand passed the Initial Checkout, as described in Initial Checkout Procedure (p. 22).

The final connections to be made or verified are:• OSSD outputs• FSD interfacing• MPCE/EDM

CAUTION: Shock Hazard

Always disconnect power from the Banner device and the guarded machine before making anyconnections or replacing any component. Use extreme caution to avoid electrical shock at all times.

5.4.1 OSSD Output ConnectionsRefer to the output specifications in the electrical specifications (see Specifications (p. 42)) and the warning below beforemaking OSSD output connections and interfacing the SGS to the machine.

WARNING: Interfacing of Both OSSDs

Both OSSD (Output Signal Switching Device) outputs must be connected to the machine control so thatthe machine’s safety-related control system interrupts the circuit to the machine primary controlelement(s), resulting in a non-hazardous condition.

Never wire an intermediate device(s) (for example, PLC, PES, or PC) that can fail in such a manner thatthere is the loss of the safety stop command, OR in such a manner that the safety function can besuspended, overridden, or defeated, unless accomplished with the same or greater degree of safety.Failure to follow these instructions could result in serious injury or death.

WARNING: OSSD Interfacing

To ensure proper operation, the Banner device output parameters and machine input parameters mustbe considered when interfacing the Banner device OSSD outputs to machine inputs. Machine controlcircuitry must be designed so that the maximum load resistance value is not exceeded and that themaximum specified OSSD Off-state voltage does not result in an On condition.

Failure to properly interface the OSSD Outputs to the guarded machine could result in serious injury ordeath.

5.4.2 FSD Interfacing ConnectionsFSDs (Final Switching Devices) take many forms. The most common are forced-guided devices, mechanically linked relays,or interface modules. The mechanical linkage between the contacts allows the device to be monitored by the ExternalDevice Monitoring circuit for certain failures.

Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSDoutputs of the SGS. FSDs can also be used to control an additional number of hazards by creating multiple safety stopcircuits.

Protective Stop (Safety Stop) CircuitsA protective stop (safety stop) allows for an orderly cessation of motion for safeguarding purposes, which results in a stopof motion and removal of power from the MPCEs (assuming this does not create additional hazards). A protective stopcircuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically linked relays, whichare monitored through External Device Monitoring to detect certain failures in order to prevent the loss of the safetyfunction. Such a circuit can be described as a "safe switching point". Typically, protective stop circuits are either single-



channel, which is a series connection of at least two normally open contacts; or dual-channel, which is a separateconnection of two normally open contacts. In either method, the safety function relies on the use of redundant contacts tocontrol a single hazard. If one contact fails On, the second contact arrests the hazards and prevents the next cycle fromoccurring. See Wiring Diagrams (p. 30).

The interfacing of the protective stop circuits must be accomplished so that the safety function cannot be suspended,overridden, or defeated, unless accomplished in a manner of the same or greater degree of safety as the machine’s safetyrelated control system that includes the SGS.

The normally open safety outputs from an interface module provide a series connection of redundant contacts that formprotective stop circuits for use in either single-channel or dual-channel control. See Wiring Diagrams (p. 30).

Dual-Channel ControlDual-channel control provides the ability to electrically extend the safe switching point beyond the FSD contacts. Withproper monitoring, this method of interfacing is capable of detecting certain failures in the control wiring between the safetystop circuit and the MPCEs. These failures include a short-circuit of one channel to a secondary source of energy orvoltage, or a loss of the switching ability of one of the FSD outputs. Such failures may lead to a loss of redundancy, or to acomplete loss of safety, if not detected and corrected.

The possibility of a failure to the wiring increases as the physical distance between the FSD safety stop circuits and theMPCEs increases, as the length or the routing of the interconnecting wires increases, or if the FSD safety stop circuits andthe MPCEs are located in different enclosures. For this reason, dual-channel control with EDM monitoring should be used inany installation where the FSDs are located remotely from the MPCEs.

Single-Channel ControlSingle-channel control uses a series connection of FSD contacts to form a safe switching point. After this point in themachine’s safety-related control system, failures can occur that would result in a loss of the safety function (such as ashort-circuit to a secondary source of energy or voltage). For this reason, single-channel control interfacing should be usedonly in installations where FSD safety stop circuits and the MPCEs are mounted within the same control panel, adjacent toeach other, and are directly connected to each other; or where the possibility of such a failure can be excluded. If thiscannot be achieved, then dual-channel control should be used.

Methods to exclude the possibility of these failures include, but are not limited to:• Physically separating interconnecting control wires from each other and from secondary sources of power• Routing interconnecting control wires in separate conduit, runs, or channels• Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each

other, and directly connected with short wires• Properly installing multi-conductor cabling and multiple wires through strain relief fittings. Over-tightening of a

strain-relief can cause short-circuits at that point.• Using positive-opening or direct-drive components, installed and mounted in a positive mode

5.4.3 Machine Primary Control Elements and EDM InputA machine primary control element (MPCE) is an electrically powered element that directly controls the normal operation ofa machine in such a way that it is the last element (in time) to function when machine operation is to be initiated or arrested(per IEC 61496-1). Examples include motor contactors, clutch/brakes, valves, and solenoids.

Depending on the level of risk of harm, it may be required to provide redundant MPCEs or other control devices that arecapable of immediately stopping the dangerous machine motion, irrespective of the state of the other. These two machinecontrol channels need not be identical (diverse redundant), but the stop time performance of the machine (Ts, used tocalculate the safety distance, see Calculating Safety Distance Formula and Examples (p. 12)) must take into account theslower of the two channels. Consult the machine manufacturer for additional information.

To ensure that an accumulation of failures does not compromise the redundant control scheme (cause a failure to danger),a method to verify the normal functioning of MPCEs or other control devices is required. The SGS system provides aconvenient method for this verification: external device monitoring (EDM).

For the SGS external device monitoring to function properly, each device must include a normally closed, forced-guided(mechanically linked) contact that can accurately reflect the status of the device. This ensures that the normally opencontacts, used for controlling hazardous motion, have a positive relationship with the normally closed monitoring contactsand can detect a failure to danger (for example, contacts that are welded closed or stuck On).

It is strongly recommended that a normally closed, forced-guided monitoring contact of each FSD and MPCE be connectedin series with the EDM input (see Generic Wiring for a Active Transceiver and IM-T-9A Interface Module (p. 32)). If this isdone, proper operation will be verified. Monitoring FSD and MPCE contacts is one method of maintaining control reliability(OSHA/ANSI) and Category 3 and 4 (ISO 13849-1).

If monitoring contacts are not available or do not meet the design requirement of being forced-guided (mechanically linked),it is recommended you:



• Replace the devices so that they are capable of being monitored; or• Incorporate the EDM function into the circuit as close to the MPCE as possible (for example, monitor the FSDs); and• Employ the use of well-tried, tested, and robust components, and generally accepted safety principles, including

fault exclusion, into the design and installation to either eliminate, or reduce to an acceptable (minimal) level of risk,the possibility of undetected faults or failures that can result in the loss of the safety function.

The principle of fault exclusion allows the designer to design out the possibility of various failures and justify it through therisk assessment process to meet the required level of safety performance, such as the requirements of Category 2, 3, or 4.See ISO 13849-1/-2 for further information.

WARNING: EDM Monitoring. If the System is configured for “No Monitoring,” it is the user’s responsibilityto ensure that this does not create a hazardous situation. Failure to follow these instructions could resultin serious injury or death.

5.4.4 External Device MonitoringSGS provides two possible EDM configurations: 1-channel monitoring and no monitoring. Their functions are describedbelow. The most common form of EDM is 1-channel monitoring; its primary advantages is the simplicity of wiring. Theinstallation must prevent short circuits across the N.C. monitoring contacts and to secondary sources of power.

External Device Monitoring WiringIf not connected previously, it is again strongly recommended that one normally closed, forced-guided monitoring contactof each FSD and MPCE be wired as shown in the monitoring circuit (see Generic Wiring for a Active Transceiver and IM-T-9A Interface Module (p. 32)). The orange wire of the active transceiver connector provides connection for the externaldevice monitoring input.

External device monitoring (EDM) must be wired in one of two configurations described below.

One-Channel Monitoring: This is a series connection of normally closed monitor contacts that are force-guided(mechanically linked) from each device controlled by the SGS. The monitor contacts must be closed before the SGS OSSDscan turn on. After the safety outputs (OSSDs) turn on, the monitor contacts must open in 350 ms. However, the monitorcontacts must be closed within 100 ms of the OSSD outputs going from on to off.

Refer to Initial Electrical Connections (p. 22) for wiring. Connect the monitor contacts between +24 V dc and EDM (orangewire).

No Monitoring: Use this configuration to perform the initial checkout; see Initial Checkout Procedure (p. 22). If theapplication does not require the EDM function, it is the user's responsibility to ensure that this configuration does not createa hazardous situation.

To configure the SGS Safety Grid System for no monitoring, see System Configuration Settings (p. 33).

WARNING:• Retrofit of 2-channel EDM Installations. If there are any questions concerning retrofit installations,

contact Banner Engineering.• If the required wiring changes are not made, the device connected to pin 2 (Orn/Blk) will not be

monitored and could result in undetected faults and create an unsafe condition, which couldresult in serious bodily injury or death.

• In existing installations using 2-channel external device monitoring (default setting of EZ-SCREEN), rewire the parallel wiring of the N.C. monitoring contacts for the series connectionused for 1-channel EDM.



5.4.5 Preparing for System OperationAfter the initial trip test has been accomplished, and the OSSD safety outputs and EDM connections have been made to themachine to be controlled, the SGS is ready for testing in combination with the guarded machine.

The operation of the SGS with the guarded machine must be verified before the combined System and machine may be putinto service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure.

not install suppressors directly across the output contacts of the safety or interface module. Insuch a configuration, it is possible for suppressors to fail as a short circuit.




6 System Operation

6.1 Security ProtocolCertain procedures for installing, maintaining, and operating the SGS must be performed by either Designated Persons orQualified Persons.

A Designated Person is identified and designated in writing, by the employer, as being appropriately trained and qualified toperform system resets and the specified checkout procedures on the SGS. The Designated Person is empowered to:

• Perform manual resets and hold possession of the reset key• Perform the Daily Checkout Procedure

A Qualified Person, by possession of a recognized degree or certificate of professional training, or by extensive knowledge,training, and experience, has successfully demonstrated the ability to solve problems relating to the installation of the SGSSystem and its integration with the guarded machine. In addition to everything for which the Designated Person isempowered, the Qualified Person is empowered to:

• Install the SGS System• Perform all checkout procedures• Make changes to the internal configuration settings• Reset the System following a Lockout condition

6.2 System Configuration SettingsThere is a configuration panel on the top of the active transceiver. Do not lose or misplace the gasket under the whiteplastic cover. Installing the cover without the gasket lowers the environmental rating.

To change the configuration settings:

1. Remove power from the device.2. Unscrew the white plastic cover from the top of the unit.3. Make the desired changes on the configuration panel.4. Reinstall the white plastic cover and gasket to maintain NEMA/IP ratings.

Active Transceiver SettingsDIP Switches

Manual start/restart Output Mode ON

Auto start/restart Output Mode OFF

EDM Mode: Monitoring via Pin 3 (orange wire) ON

EDM Mode: No Monitoring OFF

The DIP switches are in the on position (default position) when the switch is away from the numbers and in the off positionwhen the switch is toward the numbers.

If Automatic Start/Restart (Trip Output) is selected, the output signal switching device (OSSD) outputs turn on after power isapplied, and the active transceiver passes its internal self-test/synchronization and recognizes that all beams are clear. TheOSSD outputs also turn on after all beams are cleared following a blocked beam.

If Manual Start/Restart (Latch Output) is selected, the SGS requires a manual reset for the OSSD outputs to turn on whenpower is applied and all beams are clear or after a blocked beam has been cleared.



6.3 Reset ProceduresPerform system resets using an external reset switch.

Mount the reset switch outside the guarded area and not within reach from within the guarded area. Its location shouldprovide a clear view of the entire safeguarded area. If any hazardous areas are not in view from the switch location,additional means of safeguarding must be provided. Protect the switch from accidental or unintended actuation (forexample, through the use of rings or guards).

If supervisory control of the reset switch is required, a key switch may be used, with the key kept in the possession of aDesignated or Qualified Person. Using a key switch provides some level of personal control, since the key may be removedfrom the switch. This hinders a reset while the key is under the control of an individual, but must not be relied upon solely toguard against accidental or unauthorized reset. Spare keys in the possession of others or additional personnel entering thesafeguarded area unnoticed may create a hazardous situation.

Receiver manual resets are required in the following situations:• Automatic Start/Restart—Only after specific types of lockouts• Manual Start/Restart—At power-up, after each block condition is cleared, or after specific types of lockouts

6.3.1 Reset the Receiver or Active Transceiver After a LockoutFollow these reset instructions to return the SGS receiver or active transceiver to its active state.

Use this reset procedure to reset the receiver or active transceiver from the following lockout conditions:• Output Fault• Optic Fault• EDM Fault

1. Correct the condition that caused the lockout2. Hold the reset line open for a minimum of 5 seconds.3. If the fault is not cleared, turn off the power for 10 seconds, then turn the power back on.

6.3.2 Reset in Manual Start/Restart ModeFollow these steps to reset your SGS Safety Grid System in Manual Start/Restart mode at startup or after a lockout.

1. Clear all beams from the condition that caused the lockout.

If you are starting your SGS, ignore this step.2. Hold the reset line open for a minimum of 0.5 seconds.3. Close the reset line.

The reset cycle is complete.

6.4 Normal Operation

6.4.1 System Power-UpWhen power is applied, the active transceiver conducts self-tests to detect critical internal faults, determine configurationsettings, and prepare the SGS for operation.

If the active transceiver detects a critical fault, scanning ceases, the active transceiver outputs remain off, and diagnosticinformation displays on the sensor’s Diagnostic Display.

If no faults are detected, the SGS active transceiver enters Run mode and if it is aligned with a mirror assembly, it beginsscanning to determine the status (blocked or clear) of each couple.

6.4.2 Run ModeIf either couple becomes blocked when the SGS is running, the active transceiver outputs turn Off within the stated SGSresponse time (see Specifications (p. 42)). If all the beams then become clear, the active transceiver outputs come backOn. No resets are needed if the SGS is in Auto Start/Restart mode. If the system is in Manual Start/Restart mode, manuallyreset the system. All required machine control resets are provided by the machine control circuit.



Internal Faults (Lockouts): If the active transceiver detects a critical fault, scanning ceases, the active transceiver outputsturn off, and diagnostic information displays on the sensor’s Diagnostic Display. See Lockout Conditions (p. 38) forresolution of error/fault conditions.

6.5 Periodic Checkout RequirementsTo ensure continued reliable operation, the System must be checked out periodically. Banner Engineering highlyrecommends performing the System checkouts as described below. However, a Qualified Person should evaluate theserecommendations, based on the specific application and the results of a machine risk assessment, to determine theappropriate content and frequency of checkouts.

At every shift change, power-up, and machine setup change, the Daily Checkout should be performed; this checkout maybe performed by a Designated or Qualified Person.

Semi-annually, the System and its interface to the guarded machine should be thoroughly checked out; this checkout mustbe performed by a Qualified Person (see Checkout Procedures (p. 40)). A copy of these test results should be posted onor near the machine.

Whenever changes are made to the System (either a new configuration of the SGS System or changes to the machine),perform the Commissioning Checkout.

Note: Verify Proper Operation

The SGS can operate as it is designed only if it and the guarded machine are operating properly, bothseparately and together. It is the user’s responsibility to verify this, on a regular basis, as instructed in Checkout Procedures (p. 40). Failure to correct such problems can result in an increased risk of harm.

Before the System is put back into service, verify that the SGS System and the guarded machine performexactly as outlined in the checkout procedures and any problem(s) are found and corrected.

8.3 Recovery ProcedureTo recover from a lockout condition, follow these steps.

WARNING: Shut Down Machinery Before Servicing

The machinery to which the Banner device is connected must not be operating at any time during majorservice or maintenance. This may require lockout/tagout procedures (refer to OSHA1910.147, ANSIZ244-1, ISO 14118 or the appropriate standard for controlling hazardous energy). Servicing the Bannerdevice while the hazardous machinery is operational could result in serious injury or death.

WARNING: Lockouts and Power Failures

Power failures and Lockout conditions are indication of a problem and must be investigated immediatelyby a Qualified Person6. Attempts to continue to operate machinery by bypassing the Banner device orother safeguards is dangerous and could result in serious injury or death.

1. Correct all errors.2. If the lockout is non-recoverable:

a) Remove power from the sensor and wait a few seconds.b) Apply power to the sensor.

3. If the lockout is recoverable: Hold the reset line open for 5 seconds, then release it.After a few seconds, the SGS performs a self check. If all faults are cleared, the SGS resumes functioning.

8.4 Electrical and Optical NoiseThe SGS is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably inindustrial settings. However, serious electrical and/or optical noise may cause a random Trip. In very extreme electricalnoise cases, a Lockout is possible. To minimize the effects of transitory noise, the SGS dual scan technology responds tonoise only if the noise is detected on multiple consecutive scans.




If random nuisance Trips occur, check the following:• Poor connection between the sensor and earth ground• Optical interference from adjacent light screens or other photoelectrics• Sensor input or output wires routed too close to noisy wiring

8.4.1 Check for Sources of Electrical NoiseIt is important that the light screen sensors have a good earth ground. Without this, the System can act like an antenna andrandom Trips and Lockouts can occur.

All SGS wiring is low voltage; running these wires alongside power wires, motor/servo wires, or other high-voltage wiringcan inject noise into the SGS System. It is good wiring practice (and may be required by code) to isolate SGS wires fromhigh-voltage wires.

1. Use the Banner model BT-1 Beam Tracker Alignment Aid to detect electrical transient spikes and surges.2. Cover the lens of the BT-1 with electrical tape to block optical light from entering the receiver lens.3. Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the SGS or any other nearby

wires.4. Install proper transient suppression across the load to reduce the noise.

8.4.2 Check for Optical Noise SourcesTo check for optical noise sources, follow these steps.

1. Completely block the emitter portion of a couple (on a two-beam system, the emitting side of the couple is near thetop of the housing, opposite the QD; for multiple couple systems, the emitter portions of each couple are toward thecenter of the housing).

2. Use a Banner BT-1 Beam Tracker (see Accessories (p. 44)) to check for light at the receiver portion of a couple (ona two-beam system, the receiving side is near the QD; for multiple couple systems, the receivers are near the endcaps)..

3. Press the RCV button on the BT-1 and move around near the end caps of the unit.4. If the BT-1’s indicator lights up, check for emitted light from other sources (other safety light screens, grids or

points, or standard photoelectric sensors).



9 Checkout ProceduresThis section lists the schedule of checkout procedures and describes where each procedure is documented. Checkoutsmust be performed as described. Results should be recorded and kept in the appropriate place (for example, near themachine, and/or in a technical file).

Banner Engineering highly recommends performing the System checkouts as described. However, a qualified person (orteam) should evaluate these generic recommendations considering their specific application and determine the appropriatefrequency of checkouts. This will generally be determined by a risk assessment, such as the one contained in ANSI B11.0.The result of the risk assessment will drive the frequency and content of the periodic checkout procedures and must befollowed.

9.2 Perform a Commissioning CheckoutPerform a commissioning checkout as part of the System installation after the System has been interfaced to the guardedmachine, or after changes are made to the System (either a new configuration of the SGS or changes to the machine). AQualified Person must perform the procedure. Checkout results should be recorded and kept on or near the guardedmachine as required by applicable standards.

WARNING: Do Not Use Machine Until System Is Working Properly

If all of these checks cannot be verified, do not attempt to use the safety system that includes the Bannerdevice and the guarded machine until the defect or problem has been corrected. Attempts to use theguarded machine under such conditions could result in serious injury or death.

1. Examine the guarded machine to verify that it is of a type and design compatible with the SGS System. See Examples: Inappropriate Applications (p. 8) for a list of misapplications.

2. Verify the SGS is configured for the intended application.3. Verify the safety distance (minimum distance) from the closest danger point of the guarded machine to the sensing

field is not less than the calculated distance, per Mechanical Installation (p. 11).






4. Verify:

a) Access to any dangerous parts of the guarded machine is not possible from any direction not protected by theSGS System, hard (fixed) guarding, or supplemental safeguarding, and

b) It is not possible for a person to stand between the sensing field and the dangerous parts of the machine, orc) Supplemental safeguarding and hard (fixed) guarding, as described by the appropriate safety standards, are in

place and functioning properly in any space (between the sensing field and any hazard) which is large enough toallow a person to stand undetected by the SGS.

5. Verify all reset switches are mounted outside and in full view of the guarded area, out of reach of anyone inside theguarded area, and that means of preventing inadvertent use is in place.

6. Examine the electrical wiring connections between the SGS OSSD outputs and the guarded machine’s controlelements to verify that the wiring meets the requirements stated in Electrical Connections to the Guarded Machine(p. 27).

7. Inspect the area near the sensing field (including work pieces and the guarded machine) for reflective surfaces (see Adjacent Reflective Surfaces (p. 15)). Remove the reflective surfaces if possible by relocating them, painting,masking or roughening them. Remaining problem reflections will become apparent during the Trip Test.

8. Verify power to the guarded machine is Off. Remove all obstructions from the sensing field. Apply power to the SGSSystem.

9. Observe the Status indicators and Diagnostic Display:

• Lockout: Error code on display• Blocked: Red Status indicator is on• Clear: Green Status is on

10. A Blocked condition indicates that one or more of the beams is misaligned or interrupted. See Optically Align theComponents in the Initial Checkout Procedure (p. 22) section to correct this situation.

11. After the green Status indicator is on, conduct a trip test on each sensing field to verify proper System operation andto detect possible optical short circuits or reflection problems. Do not continue until the SGS passes the trip test.

Important: Do not expose any individual to any hazard during the following checks.

WARNING: Before Applying Power to the Machine

Verify that the guarded area is clear of personnel and unwanted materials (such as tools) beforeapplying power to the guarded machine. Failure to follow these instructions could result inserious injury or death.

12. Apply power to the guarded machine and verify the machine does not start up.13. Interrupt (block) the sensing field with a 60 mm, opaque, cylindrical test piece (not supplied) and verify it is not

possible for the guarded machine to be put into motion while the beam(s) is blocked.14. Initiate machine motion of the guarded machine and, while it is moving, use the test piece to block a beam. Do not

attempt to insert the test piece into the dangerous parts of the machine.Upon blocking any beam, the dangerous parts of the machine must come to a stop with no apparent delay.

15. Remove the test piece from the beam. Verify the machine does not automatically restart and the initiation devicesmust be engaged to restart the machine.

16. Remove electrical power to the SGS.Both OSSD outputs should immediately turn Off, and the machine must not be capable of starting until power is re-applied to the SGS.

17. Test the machine stopping response time, using an instrument designed for that purpose, to verify it is the same orless than the overall system response time specified by the machine manufacturer.

Do not continue operation until the entire checkout procedure is complete and all problems are corrected.

12 GlossaryA

ANSI (American National Standards Institute)Acronym for the American National StandardsInstitute, an association of industry representativesthat develops technical standards (including safetystandards). These standards comprise a consensusfrom a variety of industries on good practice anddesign. ANSI standards relevant to application ofsafety products include the ANSI B11 Series, andANSI/RIA R15.06. See Standards and Regulations (p.5).

Auto Power-UpA safety light screen system feature that enables thesystem to be powered up into Run mode (or recoverfrom a power interruption) without requiring a manualreset.

Auto Start/Restart (Trip) ConditionThe safety outputs of a safety light screen systemturn off when an object completely blocks a beam. Inan Auto Start/Restart condition, the safety outputsre-energize when the object is removed from thedefined area.

Auto Start/Restart (Trip) InitiateThe resetting of a safeguard causing the initiation ofmachine motion or operation. Auto Start/RestartInitiate is not allowed as a means to initiate amachine cycle per NFPA 79 and ISO 60204-1, and iscommonly confused with PSDI.

B

BlankingA programmable feature of a safety light screensystem which allows the light screen to ignore certainobjects located within the defined area. See FloatingBlanking and Reduced Resolution.

Blocked ConditionA condition that occurs when an opaque object ofsufficient size blocks/interrupts one or more lightscreen beams. When a blocked condition occurs,OSSD1 and OSSD2 outputs simultaneously turn offwithin the system response time.

BrakeA mechanism for stopping, slowing, or preventingmotion.

C

CascadeSeries connection (or "daisy-chaining") of multipleemitters and receivers.

CEAbbreviation for "Conformité Européenne" (Frenchtranslation of "European Conformity"). The CE markon a product or machine establishes its compliancewith all relevant European Union (EU) Directives andthe associated safety standards.

ClutchA mechanism that, when engaged, transmits torqueto impart motion from a driving member to a drivenmember.

Control ReliabilityA method of ensuring the performance integrity of acontrol system or device. Control circuits aredesigned and constructed so that a single failure orfault within the system does not prevent the normalstopping action from being applied to the machinewhen required, or does not create unintendedmachine action, but does prevent initiation ofsuccessive machine action until the failure iscorrected.

CSAAbbreviation for Canadian Standards Association, atesting agency similar to Underwriters Laboratories,Inc. (UL) in the United States. A CSA-certifiedproduct has been type-tested and approved by theCanadian Standards Association as meetingelectrical and safety codes.

D

Defined AreaThe "screen of light" generated by a safety lightscreen system, defined by the height and the safetydistance (minimum distance) of the system.

Designated PersonA person or persons identified and designated inwriting, by the employer, as being appropriatelytrained and qualified to perform a specified checkoutprocedure.



E

EmitterThe light-emitting component of a safety light screensystem, consisting of a row of synchronizedmodulated LEDs. The emitter, together with thereceiver (placed opposite), creates a "screen of light"called the defined area.

External Device Monitoring (EDM)A means by which a safety device (such as a safetylight screen) actively monitors the state (or status) ofexternal devices that may be controlled by the safetydevice. A lockout of the safety device will result if anunsafe state is detected in the external device.External device(s) may include, but are not limited to:MPCEs, captive contact relays/contactors, andsafety modules.

F

Failure to DangerA failure which delays or prevents a machine safetysystem from arresting dangerous machine motion,thereby increasing risk to personnel.

Final Switching Device (FSD)The component of the machine’s safety-relatedcontrol system that interrupts the circuit to themachine primary control element (MPCE) when theoutput signal switching device (OSSD) goes to theOFF-state.

FMEA (Failure Mode and Effects Analysis)A testing procedure by which potential failure modesin a system are analyzed to determine their results oreffects on the system. Component failure modes thatproduce either no effect or a Lockout condition arepermitted; failures which cause an unsafe condition(a failure to danger) are not. Banner safety productsare extensively FMEA tested.

G

Guarded MachineThe machine whose point of operation is guarded bythe safety system.

H

Hard (Fixed) GuardScreens, bars, or other mechanical barriers affixed tothe frame of the machine intended to prevent entryby personnel into the hazardous area(s) of a machine,while allowing the point of operation to be viewed.The maximum size of the openings is determined bythe applicable standard, such as Table O-10 ofOSHA 29CFR1910.217, also called a "fixed barrierguard."

HarmPhysical injury or damage to the health of people,which may result through direct interaction with themachine or through indirect means, as a result ofdamage to property or to the environment.

Hazard PointThe closest reachable point of the hazardous area.

Hazardous AreaAn area that poses an immediate or impendingphysical hazard.

I

Internal LockoutA Lockout condition that is due to an internal safetysystem problem. Generally, indicated by the redStatus indicator LED (only) flashing. Requires theattention of a Qualified Person.

K

Key Reset (Manual Reset)

A key-operated switch used to reset a safety lightscreen system to RUN mode following a Lockoutcondition. Also refers to the act of using the switch.



L

Lockout ConditionA safety light screen condition that is automaticallyattained in response to certain failure signals (aninternal lockout). When a Lockout condition occurs,the safety light screen’s safety outputs turn Off; thefailure must be corrected and a manual reset isrequired to return the system to Run mode.

M

Machine Primary Control Element (MPCE)An electrically powered element, external to thesafety system, which directly controls the machine’snormal operating motion in such a way that theelement is last (in time) to operate when machinemotion is either initiated or arrested.

Machine Response TimeThe time between the activation of a machinestopping device and the instant when the dangerousparts of the machine reach a safe state by beingbrought to rest.

Manual Start/Restart (Latch) ConditionThe safety outputs of a safety light screen systemturn off when an object completely blocks a beam. Ina Manual Start/Restart condition, the safety outputsstay off when the object is removed from the definedarea. To re-energize the outputs, perform a propermanual reset.

Minimum Object Sensitivity (MOS)The minimum-diameter object that a safety lightscreen system can reliably detect. Objects of thisdiameter or greater will be detected anywhere in thedefined area. A smaller object can pass undetectedthrough the light if it passes exactly midway betweentwo adjacent light beams. Also known as MODS(Minimum Object Detection Size). See also SpecifiedTest Piece.

MutingThe automatic suspension of the safeguardingfunction of a safety device during a non-hazardousportion of the machine cycle.

O

Off StateThe state in which the output circuit is interruptedand does not permit the flow of current.

On StateThe state in which the output circuit is complete andpermits the flow of current.

OSHA (Occupational Safety and Health Administration)A U.S. Federal agency, Division of the U.S.Department of Labor, that is responsible for theregulation of workplace safety.

OSSDOutput Signal Switching Device. The safety outputsthat are used to initiate a stop signal.



P

Part-Revolution ClutchA type of clutch that may be engaged or disengagedduring the machine cycle. Part-revolution clutchedmachines use a clutch/brake mechanism, which canarrest machine motion at any point in the stroke orcycle.

Pass-Through HazardA pass-through hazard is associated withapplications where personnel may pass through asafeguard (which issues a stop command to removethe hazard), and then continues into the guardedarea, such as in perimeter guarding. Subsequently,their presence is no longer detected, and the relateddanger becomes the unexpected start or restart ofthe machine while personnel are within the guardedarea.

Point of OperationThe location of a machine where material or aworkpiece is positioned and a machine function isperformed upon it.

PSDI (Presence-Sensing Device Initiation)An application in which a presence-sensing device isused to actually start the cycle of a machine. In atypical situation, an operator manually positions apart in the machine for the operation. When theoperator moves out of the danger area, the presencesensing device starts the machine (no start switch isused). The machine cycle runs to completion, andthe operator can then insert a new part and startanother cycle. The presence sensing devicecontinually guards the machine. Single-break modeis used when the part is automatically ejected afterthe machine operation. Double-break mode is usedwhen the part is both inserted (to begin theoperation) and removed (after the operation) by theoperator. PSDI is commonly confused with "TripInitiate." PSDI is defined in OSHA CFR1910.217.Banner safety light screen systems may not be usedas PSDI devices on mechanical power presses, perOSHA regulation 29 CFR 1910.217.

Q

Qualified PersonA person who, by possession of a recognized degreeor certificate of professional training, or who, byextensive knowledge, training and experience, hassuccessfully demonstrated the ability to solveproblems relating to the subject matter and work.

R

ReceiverThe light-receiving component of a safety lightscreen system, consisting of a row of synchronizedphototransistors. The receiver, together with theemitter (placed opposite), creates a "screen of light"called the defined area.

ResetThe use of a manually operated switch to restore thesafety outputs to the On state from a lockoutcondition.

ResolutionSee Minimum Object Sensitivity.



S

Self-Checking (Circuitry)A circuit with the capability to electronically verifythat all of its own critical circuit components, alongwith their redundant backups, are operating properly.Banner safety light screen systems and safetymodules are self-checking.

Safety DistanceThe minimum distance required to allow themachine’s hazardous motion to stop completely,before a hand (or other object) can reach the nearesthazard point. Measured from the midpoint of thedefined area to the nearest hazard point. Factors thatinfluence minimum separation distance include themachine stop time, the light screen system responsetime, and the light screen minimum object detectionsize.

Specified Test PieceAn opaque object of sufficient size used to block alight beam to test the operation of a safety lightscreen system. When inserted into the defined areaand placed in front of a beam, the test piece causesthe outputs to de-energize.

Supplemental GuardingAdditional safeguarding device(s) or hard guarding,used to prevent a person from reaching over, under,through or around the primary safeguard orotherwise accessing the guarded hazard.
